Three
devices are available from the
Microsoft online store: the HTC HD7 for T-Mobile, the HTC
Surround for AT&T, and the Samsung Focus for AT&T. Any of the
three devices will run you $199.99 on a qualifying two-year contract.
All three are comparable in terms of specs. They vary slightly in
screen size (4.3" HD7, 4.0" Focus, 3.8" Surround),
and the
Surround sports a slide-out Dolby speaker for enhanced audio
performance.

The Dell
online store is offering all three devices for only $149.99,
and also boasts the full-QWERTY LG Quantum for AT&T (currently
out of stock) for the same price. Prices fall to as low as $99 over
at the
Amazon Wireless Store.

Initial
sales, though not always an indication of how a product will do (see:
Android and the T-Mobile G1), will undoubtedly be closely watched by
Microsoft and its competitors. Here's hoping WP7 fares better
than Microsoft's
last big mobile launch.
